WILLIAM L. BURNER, OF COLUMBUS, OHIO, ASSIGNOB TO KILBOURNE ANDv JACOBS MANUFACTURING COMPANY, COLUMBUS, OHIO, A CORPORATION OF OHIO DUMP-CAR.

l To all tohom it may concern:

@Be it known that 1, WI LIAM L. BORNER," a citizen of the UnitedStates, resid ng at Columbus, in the county of Franklin and State of Ohio, have invented vcertain new,

and useful Improvements in Dump-Cars, of which the following is a specification.

My invention relates to improvements in dump carsand comprises door operating mechanism especiallyapplicable to cars having displaceable sides; myi devices not only hold the door aloft as the earbed is being dumped and righted, but also have a lateral travel imparted thereto to effect a quick and Wide opening between the door, and the car bed. The peculiar arrangement of'supporting bars and other operating ba'rs-wlll be pointed out in detail later.. 1

In th drawing which is hereto attached and hereby made a part of the SPGCIfiC atIOII an end view of a car is presented having a car bed 1 pivotally mounted at 2 to permit lateral dumping, on the underframe- 3; on said 'underframe disposed 1 transversely thereof is the track or guide lfor supportv ing the dumping devices and providinga guide for the latter in their movements dur-' c 6, ,9, and while the upperend of the bar 11 ingthe dumping operation; I

The door 5 extending as usual thelength of the car is supported by the vbar 6 pivotally connected with the car'bed near the middle point of the upper edgethereof at 7, and bar 6 is pivotally connected to the door at a point 8 about halfway between the upper and lower edges thereof. A 'second bar 9 is pivotally'connected with the door at 10, a point near theupper edge thereof, and at its lower end said bar 9 1S pivoted on a vertical bar ll at 12, said bar 11 being pivotally connected atits upper end with bar 6 at a point 13 near the middle point longitudinally but between said middle point and the door.

At 12 also 1s plvotally connected with vertical bar 11 and door supporting bar 9 a.-

thrust member or bar 14 which at its other end is pivotally mounted onthe car bed at 15. Disposed on bar ll'toward the lower end thereof is a roller or wheel 16 adapted to engage the track member 4 as the car bed is being tilted, and to act thereupon and thereafter during the tilting .andrighting operations as a prop for the door supporting mechanisms.

As the car bedis tilted, as appears in the Specification of Letters Patent,

of the carbed, the lower end is also being .tively.

figure in the dottedlines, the car bed, door,

and door operating mechanism travel as an integral structure until the roller 16 contacts with the track 4, whereupon the bar 11 throughthe pivotal connections12, l3 prevents a further descent of the door supporting members 6,9. The door is thereby maintained at about the altitude .thus reached and as the car bed continues to descend the whole door-supporting structure is given a thrust outwardly by the 'bar 14 approaching a horizontal'position and as a result the whole-structure moves laterally carrying the door away from thecar bed through a distance determined by the lengths of thebar members 6, 14.., In this porting bar 11 has been brought almost into vertical coincidence with supporting bar 9..

When the car bed is being righted the door supporting structure de-. scribed is drawn back by its connection its normal closedposition. It willbe noted that the roller provision and the intercon- '80 capable most effectively to exert a. lifting 9,0 therewith and the door is thereby restored to necti'on among the ba rs used in this mecha-.
